Q&As 

HDD Status 

Q:

 What are the indications of HDD status, reflected by the hidden LED? 

A:

 When connected, the hidden LED will light up and one small part on the lid 

toward its Front View will become steadily blue.  If the HDD is being accessed, 
the hidden LED at the same place will flash in blue. 

File System Format 

Q:

 I would like to format my hard drives with the FAT (a.k.a. File Allocation 

Table) format, which can be read and written by both Mac and PC.  Is there 
any limitation on its capacity?  

A:

 Yes, please check the table below for reference. 

 

File System 

NTFS 

FAT32

Win2000 / 
WinXP)

Discrepancy in Reported & Actual Size Capacity 

Q:

 If I have a 320GB HDD, why does the Enclosure only recognizes the HDD 

available space as to be less than 320GB?  

A:

 Many customers are confused by their host systems when it reports a 

discrepancy between reported capacity and actual capacity.  Several factors 
can come into play when your host system views and reports the capacity of a 
hard drive.  There are actually two different numbering systems used to 
express units of storage capacity:  
 
  

Binary

, which says that a kilobyte is equal to 1024 bytes; and  

  

Decimal

, which says that a kilobyte is equal to 1000 bytes.  

 
Most commonly used to display storage capacity is in Decimal.  The 
surprising fact is that even though it seems like you will have more bytes 
under Binary, the Decimal calculation system actually presents a greater 
storage capacity.  More information on capacity issues can be found at the 
Seagate website under FAQs.
